External portable hard drive not showing up on WD Tv Live Plus 3gen

Hi, I just bought the WD TV Live plus and I am having some external hard drive issues. The hard drive does not show up after plugging it in and out numerous times. The 500gb hard drive only shows up when I reformat my hard drive to NTFS but after the first time the WD Tv device doesnt seem to find it ever again. Please help me through this. All FAT 32 usb drives are working. Its just the NTFS format doesnt work after the first time it is plugged in. Please provide some solutions or tips. Thanks
